FORMAT
Format:HTML list | Settings

FIELDS
(content referenced) Content: Title   

RELATIONSHIPS
Entity Reference: Spotlight Content

CONTEXTUAL FILTERS
Content: Nid                       

NOTE (More on Contextual Filters!!)   
do provide default value: "Content ID from URL"



Seemed like this works also if you select "PHP…":
$node = menu_get_object();
if($node->nid){
return $node->nid;}
else{
return null;
}
